Chloro(pentamethylcyclopentadienyl)(cyclooctadiene)ruthenium(II) is a homogeneous catalyst for the formation of carbon-carbon and carbon-heteroatom bonds.
It can be used:
- To catalyze cyclotrimerization of alkynylboronates, propargyl alcohols, and terminal alkynes to form arylboronate, which in turn undergoes palladium(II)-catalyzed carbonylation to form highly substituted phthalides.
- To catalyze C-C coupling of norbornenes and norbornadiene with alkynes?to form [2 + 2] cycloadducts.
- In combination with 2-diphenylphosphinoethylamine-potassium tertiary butoxide to form a ternary catalyst system that can catalyze fast racemization of chiral non-racemic sec-alcohols.
- To synthesize new organoruthenium complexes with phosphorus-based ligands such as bis(phosphino)amines.
- To catalyze the addition of organic disulfides to alkenes leading to vic-dithioethers.
